Turning Tides is the naval expansion. Cape Helles is an amphibious landing under the guns of a dreadnought; Achi Baba the ridge fight inland from it; Zeebrugge a night raid on a harbour mole; and Heligoland Bight a map fought almost entirely on and over the water between the British and German fleets. The L-Class destroyer is a player-crewed warship, and Conquest Assault gives the defenders all flags at the start and the attackers the task of taking them.

The Gallipoli Operation links the two Turkish maps.

Cape Helles rewards attackers who land wide of the beach and use the dreadnought’s guns; Achi Baba is a ridge fight where height wins. Zeebrugge is close, dark and confused, the best infantry map of the set. Heligoland Bight belongs to destroyer crews and pilots; infantry on the islands are a sideshow. Conquest Assault is an attacker’s mode on paper and a defender’s in practice: the side that keeps two flags and bleeds the attack wins.
